Answer

$-40.0 ^{\circ}C$

Work Step by Step

We know that the equation to convert from Celsius to Fahrenheit is given by: $T(F) = (1.8 \times T(c)) +32$ Contrarily, if we want to convert from Fahrenheit to Celsius, we use the formula: $T(c) = \frac{(T(F) -32)}{1.8}$ Once we know this, we plug in the given value. We simplify using a calculator, remembering parentheses, to obtain the answer: $-40.0 ^{\circ}C$
